Analisis Karakteristik Fungsi Lagrange Dalam Menyelesaikan Permasalahan Optimasi Berkendala

Abstract: Optimasi adalah suatu aktivitas untuk mendapatkan hasil terbaik di dalam suatu keadaan yang diberikan. Tujuan akhir dari aktivitas tersebut adalah meminimumkan usaha (effort) atau memaksimumkan manfaat (benefit) yang diinginkan. Metode pengali Lagrange merupakan metode yang digunakan untuk menangani permasalahan optimasi berkendala. Pada penelitian ini dianalisis karakteristik dari metode pengali Lagrange sehingga metode ini dapat menyelesaikan permasalahan optimasi berkendala. Metode tersebut diaplikasikan pa… Show more

“…Classification of Support Vector Machine algorithms obtained kernel models with weights from each attribute as in Table 2where the results of the optimization of the margin used to maximize the distance between hyperplane with the closest pattern had a bias value (offset) of 0.946. The next step after initiating and obtaining the value of w is to add an optimization method called Lagrange multipliers which can transform problem constraints into no constraints and is used to perform nonlinear functions in solving optimization problems [30] which then produces positive values derived from hyperplane from the closest distance called support vector. After obtaining the support vector results, then input normalization in the Support Vector Machine algorithm testing so that it produced an accuracy of 90.10% with the results of the confusion matrix testing as in Table 3.…”

“…Kasus di atas termasuk kasus dengan satu pengali Lagrange. Untuk mendapatkan penyelesaian nilai optimal dari w, persamaan di atas diturunkan terhadap w dan kemudian hasilnya disamakan dengan nol [12]. Hasil penurunannya sebagai berikut: δL/δw =r + 2k Σw + λ 1p = 0 Dengan melakukan transpose hasil di atas, akan diperoleh : 2kΣw = r-λ1p w = 1/(2k) Σ -1 (r-λ1p) Substitusi persamaan di atas ke persamaan 1p T w =1, 1p T w = 1/(2k) 1p T Σ -1 (r-λ1p) =1 Hasilnya :…”
